Mozilla fixes Firefox 16 web browser security flaw
Mozilla has moved to fix a vulnerability in the latest version of its Firefox browser that could have allowed websites to discover what other web pages a user had visited.
After the flaw was discovered this week, version 16 of Firefox was pulled by Mozilla just 24 hours after launch, and users were urged to shift to an older version.
The flaw was said to enable a "malicious" website to track users' online activity, although Mozilla insisted that only a small number of computers were affected.
Mozilla has now addressed the issue in Firefox, which has a 20% share of the global desktop browser market according to NetMarketShare, putting it just behind Microsoft's Internet Explorer.
Users of Firefox are now offered version 16.0.1 of the browser, which does not contain the security flaw.
In a statement issued to the BBC, a Mozilla spokesman said: "We were quick to recognise the security vulnerability of Firefox 16 and took immediate action to temporarily remove the update from the current installer page.
"As a precaution we asked Firefox users to revert back to using Firefox 15.0.1 whilst we worked to fix the problem. Firefox 16 was released with updates completely 'throttled', which meant that users were not automatically updated.
"We take security issues extremely seriously and were able to address the problem with Firefox quickly with limited impact to our users."
